Abstract: Pusztai affair is the blasting fuse to global dispute about the security of GM crops. This affair shows that a three-spiral-authority structure within scientific field —— the induction of the economic interests, the might of the political union and the pressing of the systematized scientific capital，is continuously extruding and destroying the autonomy of science. Only with the aid of “reflexivity”, strengthening the automony of GM crops's research and development, and actively guiding the intervention of external factors in the field of science, can GM crops better serve the development of modern agriculture.

摘要： 普兹泰事件是全球转基因作物安全性争议的导火索。这一事件表明科学场域内三螺旋式的权力结构——经济利益的诱导、政治联盟的强势，制度化科学资本的施压，有可能挤压和破坏科学的自律性，使科学沦为少数跨国公司的牟利工具。只有通过“反观性”原则，增强科学场域的自律性，积极引导外部因素的介入，才能使转基因作物更好地服务于人类社会。
